Wanderers

Seriously, stop whatever you’re doing and WATCH THIS VIDEO. And yes, you very much want to make it full screen:

Holy. WOW.

This is one of the most wondrous and moving paeans to space exploration I have ever seen. The words of Sagan are magnificent, of course. And the effects are stunning, photo-realistic, and very compelling.

But take a moment and let this sink in: Nearly every location depicted in this video is real.These aren’t just fanciful places made up in the head of a special-effects artist; those are worlds in our solar system that actually exist. And many were based on images taken through telescopes, or probes that have physically visited these distant locales.

Every time the scene changed in the video, my jaw dropped a little further and my brain soared to a new height. Nothing in there is impossible; no faster than light travel, no wormholes. Even the space elevator shown towering over Mars and the huge cylindrical rotating colony in space (did you notice the Red Sea in it?) are problems in engineering, not physics. We can build them.

And each is a dream of mine, a thing I see when I close my eyes. Cruising through the geysers of Enceladus, skimming over Jupiter’s clouds, floating in Saturn’s rings (and note the scale of the rings in the video; the chunks of ice and the height of the rings are correct).

Right now, we can only see these adventures, these possible futures, when we dream. I choked up several times watching the video, seeing these visions laid out.

But it was that last shot, the close-up of the woman watching the airship exploring the clouds over Saturn; that was what pierced home.

For now, we send our robots, our machines into space. We learn a lot that way, and there is no end to what we can discover. But this is a human endeavor, a human adventure, and there will come a time when the views of those worlds you see in this video will no longer be science fiction.
